Abstract: The aim of this work is the study of polycarbonate for integrating dosimetry of high doses of ionizing radiation as a considerably cheaper alternative to commonly used alanine dosimetry. It is focused on the molecular mechanisms of physical and chemical processes that cause color changes of the polymer after irradiation. Simultaneously, the processes that affect the regeneration time of these optical changes were mapped. The methods of absorption optical spectroscopy, nuclear magnetic resonance and positron annihilation spectroscopy were used for these analyses. Moreover, the detected structural changes in the molecular chains of the irradiated polymer were compared to the observed changes in mechanical properties studied using uniaxial tensile testing and nanoindentation.

辐照聚碳酸酯的化学过程研究在其适用于整合高剂量剂量测定的背景下

摘要：这项工作的目的是研究聚碳酸酯用于整合高剂量电离辐射的剂量学，作为常用丙氨酸剂量学的一种相当便宜的替代方法。它侧重于导致聚合物在辐照后颜色变化的物理和化学过程的分子机制。同时，映射了影响这些光学变化的再生时间的过程。吸收光谱、核磁共振和正电子湮没光谱的方法用于这些分析。此外，将检测到的受辐照聚合物分子链的结构变化与使用单轴拉伸测试和纳米压痕研究的机械性能观察到的变化进行比较。
